000021236 520__ $$2eng$$aDeveloped videogrammetric research technique is an optical method for analysis and estimation of gas fluidized bed hydrodynamics. Videogrammetry consists of process visualization, image analysis and stochastic process analysis. The two-phase flow pattern is described by the fluctuation of grey level parameter. Research focuses on the statistical analysis of the behavior of a fluidized bed operating under bubbling to turbulent conditions. Experimental data are collected by the means of a developed dynamic image analysis technique. Study was conducted in transparent, narrow fluidization apparatus. Results show that profiles of the grey level fluctuations and its stochastic parameters are correlated with particular flow pattern. The conformity of the digital flow pattern recognition method gives 82 % reliability.
